Restricting access to custom record to employee and subordinates

Hi;

I am adding a custom record with employee as one of the fields. I would like to restrict access to the information in this table to employee and subordinates only. The restriction should include searches and reports as well.

I don't want to use the permissions tab on the record type definition since the access should be given to all employees which means I would need to add all roles, and remember to add any new role.

I also can't use the "Apply role restrictions" check box on the employee field definitions because I do not use these restrictions at the role level.
